Hello everyone!!!! 2012 Tahoe manual transmission swap?

[fozzi58]

There's a guy on TikTok I saw that put the same drivetrain in his GMT900 tahoe. I will have to look for it and post again here.

But yeah I've been considering it too. I'm super disappointed that the 4.10s I have are screaming on the highway with my 6L80. I didn't realize the final drive ratio between the T56/TR60 is much lower than the 6L80. I have 3.73's in my TA and at 80mph I am at 1800 rpm. My Burn is creeping up to 2250rpm at 80mph and thats with my 24's. When I put the 22's on with the low profile tires its over 2500rpm. That's NG for trips more than 30 mins which I do a lot of.

It would probably be easier to get a 10 speed in there but its also twice the price ($7k vs $14k)

I've spoken with someone that has a GMT900 pickup that they said they swapped. Didn't get into too much detail, but said they used all GM800 parts to do it.

They did make a Mexican GMT900 pickup, but they only put the manual behind the v6. I even found a GMT900 3500, and it had a manual with a v6.

Years ago, I even found a guy selling a K2XX reg cab pickup with a factory manual transmission, in Las Vegas. It had a mexican plate on it. I asked, and he sent me the VIN. I've posted this a few times, and never had a response from anyone that has tried to look into the parts that way.

Mexican definition of 3500 is very different from the American definition of 3500, apparently ...

Yeah.. Pretty sure it was a dually too.

Looks like the gvwr is "only" 6700 lbs. The PBV number, in units of pounds. That sounds more like a 1500 series chassis, no?

I would imagine a 3500 DRW would be at least 10,000 lbs for truck in this generation, even non-US market.
